2. Description of the Related Art

In recent years, with the rise of portable electronic devices havingcamera functionalities, the demand for an optical image capturing systemis raised gradually. The image sensing device of ordinary photographingcamera is commonly selected from charge coupled device (CCD) orcomplementary metal-oxide semiconductor sensor (CMOS Sensor). Inaddition, as advanced semiconductor manufacturing technology enables theminimization of pixel size of the image sensing device, the developmentof the optical image capturing system directs towards the field of highpixels. Therefore, the requirement for high imaging quality is rapidlyraised.

The traditional optical image capturing system of a portable electronicdevice comes with different designs, including a four-lens or afive-lens design. However, the requirement for the higher pixels and therequirement for a large aperture of an end user, like functionalities ofmicro filming and night view, or the requirement of wide view angle ofthe portable electronic device have been raised. But the optical imagecapturing system with the large aperture design often produces moreaberration resulting in the deterioration of quality in periphericalimage formation and difficulties of manufacturing, and the optical imagecapturing system with wide view angle design increases distortion ratein image formation, thus the optical image capturing system in priorarts cannot meet the requirement of the higher order camera lens module.

Therefore, how to effectively increase quantity of incoming light andview angle of the optical lenses, not only further improves total pixelsand imaging quality for the image formation, but also considers theequity design of the miniaturized optical lenses, becomes a quiteimportant issue.

The vertical coordinate axis of the characteristic diagram of modulationtransfer function represents a contrast transfer rate (values are from 0to 1). The horizontal coordinate axis represents a spatial frequency(cycles/mm; lp/mm; line pairs per mm). Theoretically, an ideal imagecapturing system can 100% show the line contrast of a photographedobject. However, the values of the contrast transfer rate at thevertical coordinate axis are smaller than 1 in the actual imagecapturing system. The transfer rate of its comparison value is less thana vertical axis. In addition, comparing to the central region, it isgenerally more difficult to achieve a fine degree of recovery in theedge region of image capturing. The contrast transfer rates (MTF values)with spatial frequencies of 55 cycles/m at the optical axis, 0.3 fieldof view and 0.7 field of view of a visible spectrum on the image planeare respectively denoted by MTFE0, MTFE3 and MTFE7. The contrasttransfer rates (MTF values) with spatial frequencies of 110 cycles/m atthe optical axis, 0.3 field of view and 0.7 field of view on the imageplane are respectively denoted by MTFQ0, MTFQ3 and MTFQ7. The contrasttransfer rates (MTF values) with spatial frequencies of 220 cycles/m atthe optical axis, 0.3 field of view and 0.7 field of view on the imageplane are respectively denoted by MTFH0, MTFH3 and MTFH7. The contrasttransfer rates (MTF values) with spatial frequencies of 440 cycles/m atthe optical axis, 0.3 field of view and 0.7 field of view on the imageplane are respectively denoted by MTF0, MTF3 and MTF7. The three fieldsof view described above are representative to the centre, the internalfield of view and the external field of view of the lens elements. Thus,they may be used to evaluate whether the performance of a specificoptical image capturing system is excellent. The design of the opticalimage capturing system of the present invention mainly corresponds to apixel size in which a sensing device below 1.12 micrometers is includes.Therefore, the quarter spatial frequencies, the half spatial frequencies(half frequencies) and the full spatial frequencies (full frequencies)of the characteristic diagram of modulation transfer functionrespectively are at least 110 cycles/mm, 220 cycles/mm and 440cycles/mm.

If an optical image capturing system needs to satisfy with the imagesaimed to infrared spectrum, such as the requirement for night visionwith lower light source, the used wavelength may be 850 nm or 800 nm. Asthe main function is to recognize shape of an object formed inmonochrome and shade, the high resolution is unnecessary, and thus, aspatial frequency, which is less than 100 cycles/mm, is used to evaluatethe functionality of the optical image capturing system, when theoptical image capturing system is applied to the infrared spectrum. Whenthe foregoing wavelength 850 nm is applied to focus on the image plane,the contrast transfer rates (MTF values) with a spatial frequency of 55cycles/mm at the optical axis, 0.3 field of view and 0.7 field of viewon the image plane are respectively denoted by MTFI0, MTFI3 and MTFI7.However, the infrared wavelength of 850 nm or 800 nm may be hugelydifferent to wavelength of the regular visible light wavelength, andthus, it is hard to design an optical image capturing system which hasto focus on the visible light and the infrared light (dual-mode)simultaneously while achieve a certain function respectively.

A thickness of a single lens element at height of ½ entrance pupildiameter (HEP) particularly affects the corrected aberration of commonarea of each field of view of light and the capability of correctingoptical path difference between each field of view of light in the scopeof ½ entrance pupil diameter (HEP). The capability of aberrationcorrection is enhanced if the thickness becomes greater, but thedifficulty for manufacturing is also increased at the same time.Therefore, it is necessary to control the thickness of a single lenselement at height of ½ entrance pupil diameter (HEP), in particular tocontrol the ratio relation (ETP/TP) of the thickness (ETP) of the lenselement at height of ½ entrance pupil diameter (HEP) to the thickness(TP) of the lens element to which the surface belongs on the opticalaxis. For example, the thickness of the first lens element at height of½ entrance pupil diameter (HEP) is denoted by ETP1. The thickness of thesecond lens element at height of ½ entrance pupil diameter (HEP) isdenoted by ETP2. The thicknesses of other lens elements are denoted inthe similar way. A sum of ETP1 to ETP6 described above is SETP. Theembodiments of the present invention may satisfy the following relation:0.3≤SETP/EIN<1.

In order to enhance the capability of aberration correction and reducethe difficulty for manufacturing at the same time, it is particularlynecessary to control the ratio relation (ETP/TP) of the thickness (ETP)of the lens element at height of ½ entrance pupil diameter (HEP) to thethickness (TP) of the lens element on the optical axis lens. Forexample, the thickness of the first lens element at height of ½ entrancepupil diameter (HEP) is denoted by ETP1. The thickness of the first lenselement on the optical axis is TP1. The ratio between both of them isETP1/TP1. The thickness of the second lens element at height of ½entrance pupil diameter (HEP) is denoted by ETP2. The thickness of thesecond lens element on the optical axis is TP2. The ratio between bothof them is ETP2/TP2. The ratio relations of the thicknesses of otherlens element in the optical image capturing system at height of ½entrance pupil diameter (HEP) to the thicknesses (TP) of the lenselements on the optical axis lens are denoted in the similar way. Theembodiments of the present invention may satisfy the following relation:0.2≤ETP/TP≤3.

A horizontal distance between two adjacent lens elements at height of ½entrance pupil diameter (HEP) is denoted by ED. The horizontal distance(ED) described above is in parallel with the optical axis of the opticalimage capturing system and particularly affects the corrected aberrationof common area of each field of view of light and the capability ofcorrecting optical path difference between each field of view of lightat the position of ½ entrance pupil diameter (HEP). The capability ofaberration correction may be enhanced if the horizontal distance becomesgreater, but the difficulty for manufacturing is also increased and thedegree of ‘miniaturization’ to the length of the optical image capturingsystem is restricted. Thus, it is essential to control the horizontaldistance (ED) between two specific adjacent lens elements at height of ½entrance pupil diameter (HEP).

In order to enhance the capability of aberration correction and reducethe difficulty for ‘miniaturization’ to the length of the optical imagecapturing system at the same time, it is particularly necessary tocontrol the ratio relation (ED/IN) of the horizontal distance (ED)between the two adjacent lens elements at height of ½ entrance pupildiameter (HEP) to the horizontal distance (IN) between the two adjacentlens elements on the optical axis. For example, the horizontal distancebetween the first lens element and the second lens element at height of½ entrance pupil diameter (HEP) is denoted by ED12. The horizontaldistance between the first lens element and the second lens element onthe optical axis is IN12. The ratio between both of them is ED12/IN12.The horizontal distance between the second lens element and the thirdlens element at height of ½ entrance pupil diameter (HEP) is denoted byED23. The horizontal distance between the second lens element and thethird lens element on the optical axis is IN23. The ratio between bothof them is ED23/IN23. The ratio relations of the horizontal distancesbetween other two adjacent lens elements in the optical image capturingsystem at height of ½ entrance pupil diameter (HEP) to the horizontaldistances between the two adjacent lens elements on the optical axis aredenoted in the similar way.

A horizontal distance in parallel with the optical axis from acoordinate point on the image-side surface of the sixth lens element atheight ½ HEP to the image plane is EBL. A horizontal distance inparallel with the optical axis from an axial point on the image-sidesurface of the sixth lens element to the image plane is BL. Theembodiments of the present invention enhance the capability ofaberration correction and reserve space for accommodating other opticalelements. The following relation may be satisfied: 0.2≤EBL/BL<1.1. Theoptical image capturing system may further include a light filtrationelement. The light filtration element is located between the sixth lenselement and the image plane. A distance in parallel with the opticalaxis from a coordinate point on the image-side surface of the sixth lenselement at height ½ HEP to the light filtration element is EIR. Adistance in parallel with the optical axis from an axial point on theimage-side surface of the sixth lens element to the light filtrationelement is PIR. The embodiments of the present invention may satisfy thefollowing relation: 0.1≤EIR/PIR≤1.1.

The height of optical system (HOS) may be reduced to achieve theminimization of the optical image capturing system when the absolutevalue of f1 is larger than f6 (|f1|>f6).

When |f2|+|f3|+|f4|+|f5| and |f1|+|f6| are satisfied with aboverelations, at least one of the second through fifth lens elements mayhave weak positive refractive power or weak negative refractive power.The weak refractive power indicates that an absolute value of the focallength of a specific lens element is greater than 10. When at least oneof the second through fifth lens elements has the weak positiverefractive power, the positive refractive power of the first lenselement can be shared, such that the unnecessary aberration will notappear too early. On the contrary, when at least one of the secondthrough fifth lens elements has the weak negative refractive power, theaberration of the optical image capturing system can be corrected andfine tuned.

The sixth lens element may have negative refractive power and a concaveimage-side surface. Hereby, the back focal length is reduced for keepingthe miniaturization, to miniaturize the lens element effectively. Inaddition, at least one of the object-side surface and the image-sidesurface of the sixth lens element may have at least one inflectionpoint, such that the angle of incident with incoming light from anoff-axis field of view can be suppressed effectively and the aberrationin the off-axis field of view can be corrected further.

FIG. 2A is aschematic view of the optical image capturing system according to thesecond embodiment of the present application, FIG. 2B is longitudinalspherical aberration curves, astigmatic field curves, and an opticaldistortion curve of the optical image capturing system in the order fromleft to right according to the second embodiment of the presentapplication. FIG. 2C is a characteristic diagram of modulation transferof a visible light according to the second embodiment of the presentapplication, and FIG. 2D is a characteristic diagram of modulationtransfer of infrared rays according to the second embodiment of thepresent application. As shown in FIG. 2A, in order from an object sideto an image side, the optical image capturing system includes anaperture stop 200, a first lens element 210, a second lens element 220,a third lens element 230, a fourth lens element 240, a fifth lenselement 250, a sixth lens element 260, an IR-bandstop filter 280, animage plane 290, and an image sensing device 292.

The first lens element 210 has positive refractive power and it is madeof plastic material. The first lens element 210 has a convex object-sidesurface 212 and a concave image-side surface 214, and both of theobject-side surface 212 and the image-side surface 214 are aspheric andhave an inflection.

The second lens element 220 has negative refractive power and it is madeof plastic material. The second lens element 220 has a convexobject-side surface 222 and a convex image-side surface 224, and both ofthe object-side surface 222 and the image-side surface 224 are asphericand have an inflection point.

The third lens element 230 has positive refractive power and it is madeof plastic material. The third lens element 230 has a convex object-sidesurface 232 and a convex image-side surface 234, and both of theobject-side surface 232 and the image-side surface 234 are aspheric. Theobject-side surface 232 has two inflection points and the image-sidesurface 234 has an inflection point.

The IR-bandstop filter 380 is made of glass material without affectingthe focal length of the optical image capturing system and it isdisposed between the sixth lens element 360 and the image plane 390.

In the optical image capturing system of the third embodiment, a sum offocal lengths of all lens elements with positive refractive power isΣPP. The following relation is satisfied: ΣPP=188.498 mm andf1/ΣPP=0.046. Hereby, it is favorable for allocating the positiverefractive power of a single lens element to other positive lenselements and the significant aberrations generated in the process ofmoving the incident light can be suppressed.

In the optical image capturing system of the third embodiment, a sum offocal lengths of all lens elements with negative refractive power isΣNP. The following relation is satisfied: ΣNP=−16.942 mm and f1/ΣNP=1.0.Hereby, it is favorable for allocating the negative refractive power ofa single lens element to other negative lens elements.

FIG. 5A is aschematic view of the optical image capturing system according to thefifths embodiment of the present application, FIG. 5B is longitudinalspherical aberration curves, astigmatic field curves, and an opticaldistortion curve of the optical image capturing system in the order fromleft to right according to the fifth embodiment of the presentapplication, FIG. 5C is a characteristic diagram of modulation transferof a visible light according to the fifth embodiment of the presentapplication and FIG. 5D is a characteristic diagram of modulationtransfer of infrared rays according to the fifth embodiment of thepresent application. As shown in FIG. 5A, in order from an object sideto an image side, the optical image capturing system includes a firstlens element 510, an aperture stop 500, a second lens element 520, athird lens element 530, a fourth lens element 540, a fifth lens element550, a sixth lens element 560, an IR-bandstop filter 580, an image plane590, and an Image sensing device 592.

The first lens element 510 has positive refractive power and it is madeof plastic material. The first lens element 510 has a convex object-sidesurface 512 and a concave image-side surface 514, and both of theobject-side surface 512 and the image-side surface 514 are aspheric.

The second lens element 520 has negative refractive power and it is madeof plastic material. The second lens element 520 has a convexobject-side surface 522 and a concave image-side surface 524, and bothof the object-side surface 522 and the image-side surface 524 areaspheric and have an inflection point.

The third lens element 530 has positive refractive power and it is madeof plastic material. The third lens element 530 has a convex object-sidesurface 532 and a convex image-side surface 534, and both of theobject-side surface 532 and the image-side surface 534 are aspheric. Theobject-side surface 532 has two inflection points and the image-sidesurface 534 has an inflection point.

The fourth lens element 540 has negative refractive power and it is madeof plastic material. The fourth lens element 540 has a concaveobject-side surface 542 and a convex image-side surface 544, and both ofthe object-side surface 542 and the image-side surface 544 are asphericand have an inflection point.

The Seventh Embodiment (Embodiment 7)

Please refer to FIG. 7A and FIG. 7B, FIGS. 7C, and 7D. FIG. 7A is aschematic view of the optical image capturing system according to theseventh Embodiment of the present application, FIG. 7B is longitudinalspherical aberration curves, astigmatic field curves, and an opticaldistortion curve of the optical image capturing system in the order fromleft to right according to the seventh Embodiment of the presentapplication, FIG. 7C is a characteristic diagram of modulation transferof a visible light according to the seventh embodiment of the presentapplication and FIG. 7D is a characteristic diagram of modulationtransfer of infrared rays according to the seventh embodiment of thepresent application. As shown in FIG. 7A, in order from an object sideto an image side, the optical image capturing system includes anaperture stop 700, a first lens element 710, a second lens element 720,a third lens element 730, a fourth lens element 740, a fifth lenselement 750, a sixth lens element 760, an IR-bandstop filter 780, animage plane 790, and an image sensing device 792.

The first lens element 710 has positive refractive power and it is madeof plastic material. The first lens element 710 has a convex object-sidesurface 712 and a concave image-side surface 714, and both of theobject-side surface 712 and the image-side surface 714 are aspheric. Theimage-side surface 714 has an inflection point.

The second lens element 720 has negative refractive power and it is madeof plastic material. The second lens element 720 has a convexobject-side surface 722 and a concave image-side surface 724, and bothof the object-side surface 722 and the image-side surface 724 areaspheric and have an inflection point.

The third lens element 730 has positive refractive power and it is madeof plastic material. The third lens element 730 has a convex object-sidesurface 732 and a convex image-side surface 734, and both of theobject-side surface 732 and the image-side surface 734 are aspheric. Theobject-side surface 732 has an inflection point.

The fourth lens element 740 has positive refractive power and it is madeof plastic material. The fourth lens element 740 has a concaveobject-side surface 742 and a convex image-side surface 744, and both ofthe object-side surface 742 and the image-side surface 744 are aspheric.The image-side surface 744 has an inflection point.

The fifth lens element 750 has negative refractive power and it is madeof plastic material. The fifth lens element 750 has a concaveobject-side surface 752 and a convex image-side surface 754, and both ofthe object-side surface 752 and the image-side surface 754 are aspheric.The image-side surface 754 has an inflection point.

The sixth lens element 760 has negative refractive power and it is madeof plastic material. The sixth lens element 760 has a convex object-sidesurface 762 and a concave image-side surface 764. The object-sidesurface 762 and the image-side surface 764 both have an inflectionpoint. Hereby, the back focal length is reduced to miniaturize the lenselement effectively. In addition, the angle of incident with incominglight from an off-axis view field can be suppressed effectively and theaberration in the off-axis view field can be corrected further.

The IR-bandstop filter 780 is made of glass material without affectingthe focal length of the optical image capturing system and it isdisposed between the sixth lens element 760 and the image plane 790.

In the optical image capturing system of the seventh Embodiment, a sumof focal lengths of all lens elements with positive refractive power isΣPP. The following relations are satisfied: ΣPP=19.725 mm andf1/ΣPP=0.314. Hereby, it is favorable for allocating the positiverefractive power of a single lens element to other positive lenselements and the significant aberrations generated in the process ofmoving the incident light can be suppressed.

In the optical image capturing system of the seventh Embodiment, a sumof focal lengths of all lens elements with negative refractive power isΣNP. The following relations are satisfied: ΣNP=−30.530 mm andf2/ΣNP=0.376. Hereby, it is favorable for allocating the negativerefractive power of a single lens element to other negative lenselements.

Please refer to the following Table 13 and Table 14.
